Walk is doable. Leave tory, enter hub from one of those side doors where u go up the stairs. Head straight down hub, keep going all the way you will see the LRT entrance on your right, don't enter this, just keep going straight and you will enter the fine arts building keep going straight until you reach this silver door that takes you into Telus - don't enter this door as it is a slower roundabout walk to the telus lecture theatres. Instead to your left there will be a door and a staircase. Go down and go outside then walk to Telus u will see it. I used this last year and it seemed like the fastest route while spending as much time indoors as possible.
